Well, lurked around the forums, thought I would give back on my experience with rust bullet for concrete on my 462 Sq Ft. garage. 2 coats of grey. There are some good things and some bad things about it:
Good:
Minimal prep work
Goes on like paint
Was able to turn it around in a weekend
Was able to put in garage back in service in 48 hours (can claimed 72 hrs, but the stuff was hard as nails and my good fortune with weather was running out)
Bad:
Cost $300, my compare too was the Rustoleum kit can do a 2.5 car garage for ~$150, decent enough kit, I helped my parents with one and it failed after 10 years and my father-in-laws did about the same, just starts to wear down. I wanted to try something that would last longer, we shall see
Appearance leaves a bit to be desired
With this product when I did the first coat had a ton of roll marks, on the 2nd coat I thinned with 4oz paint thinner per gallon, got better fill in all of divots and less roller marks. The thinning was against the can's instructions, my guess adding more thinner would have gotten better results...but the manufacture stated not to thin the product even though it is solvent based, idk seemed odd but I'm not a paint guy
A lot of my patch work is clearly visible, yes more prep work would have fixed this, but I would not go in expecting this to hide any imperfections unless you are planning on flakes or a lot more coats (I did the minimum of 2)
Other thoughts:
3 gallons just barely made it and there is no local stock around, kinda makes the project a little more stressful. At the end of #2 I really wanted to do a 3rd coat, oh well. I found a place call Ucoat It after the project they are down the road from me in Auburn Hills, MI
I am happy I got a respirator, always amazed how nice 3m stuff is I didn't realize how much off gassing there was until I pulled the respirator off. The smell isn't that not that bad, but if you are working around it for awhile best of luck without one
There are plastic rings on all of the cans, cut them off at the start
Wear gloves, mine tore at some point, one of my nails is still grey a week later
I'm happy I filled the center crack (relief joint?), it was about an inch wide and my creeper always got stuck. The epoxy I got from garage LLC was good stuff. The quart containers from Depot were perfect made 24 Oz batches (12OzA in 12oz B) had a decent work time and hardened up within 24 hours
Masking tape on either side of the crack, so happy I did this, since the RB product had poor hiding of surface imperfections at least I had a straight line down the middle vs. a patched line
I was doing more harm than good with the angle grinder and cup wheel digging into the concrete kinda gave up on it
